340 Hot Questions

Drove my barracuda to get exhaust today and in a 8 mile round trip when I pulled in my drive my engine temp was 215. After shutting it off(I have the Sniper EFI) my radiator overflow line drained a bunch of coolant (about a 70 water to 30 collant with wetter mix) I noticed that the coolant on ground was air temp. Does that seem normal? it's a stock 340 rebuild, sniper, 340 exhaust manifolds, alumn. radiator new, 180 thermo. stock fan and water pump. 65 plugs. 7 BTDC timing, thanks
